CHP 700 MHz Extenders

[kma371]

The alternate frequency is actually not for car-to-car. It is another zone in the radio with the same channel setup as primary, but it uses a different VRS frequency. Officers transmit car-to-car or car-to-station by using different NACs on the primary frequency.

As you said, the alternate frequencies are rarely used, so if people are hearing regular traffic on a VRS frequency I think it's safe to assume it's the primary.

The car and station channels are in the same zone from the documents I've seen. Same out NAC, different in NAC

Received submittal for Southern Division and Db updated accordingly.

Yes, that is what I am saying. The primary zone on the radio has car-to-car using one NAC, and car-to-station using another NAC. Both channels use the primary VRS frequency.

The alternate zone on the radio also has car-to-car using one NAC, and car-to-station using another NAC. The only difference is that both channels use the alternate VRS frequency.

 

[WayneH]

Martin is correct. There's a main VRS channel and a back-up or alternate for communicating/controlling with the VRS.

VRS's operate by channel steering. This means the freq stays the same and the NAC (or PL/DPL in other agency circumstances) controls the operation of the VRS and what's connected to the VRS in the car.

In the last week I've heard a little bit on VRS1 in Orange County. I believe it's repeating Westminster Gray 1. Also just heard VRS7 active in Corona, presumably repeating Inland Turquoise 1. Will submit to the DB when I know for sure.

Heard San Luis Obispo CHP on VRS 01 769.16875 NAC DAD with their White channel 42.56 ctcss 167.9 on March 30, 2012

Driving around the bay area today I heard the following, I do not know whe CHP channel only the area

580 Oakland VRS=5

680 Concord VRS=9

Not sure what you mean when you list like that.

Are you saying you were on 580 in Oakland when you heard it, or, the calls where on 580 in Oakland.

Newhall Heard Today On

773.53125 (7D1 NAC) CHP700CH1 CHP Base Ch 1

 

[KJ6HCB]

Interesting on the SLO hit.

So with the implementation of these new 700 Mhz extenders, will traffic on 154.905 eventually cease 100%?

It will, but years away from it happen till they pick a new car and get a 700mhz plan

I was driving on 580 in Oakland near HW 13 and heard VRS Ch 5 repeating CHP Traffic
I was driving on 680 in Concord near Willow Pass Rd and heard VRS Ch 9 repeating CHP Traffic

Today I was driving on 580 in Livermore near the Livermore airport and heard VRS Ch 1 repeating CHP Traffic. This would be a Dublioffice, I do not know about the others.

Sorry I don't know the LB channels as I have not lived in this area in a couple of years and do not have any of the chp channels in my scanner. Sorry

No prob. Just wanted to clarify

These were most likely BRONZE (Oakland) and MAROON (Contra Costa) respectively. The extenders have a limited range, so you will usually hear traffic for the same geographical area.

Northern Red 700 MHz extender

Passing through Weaverville on SR 299 tonight I practically got entangled in a Trinity Co SO/CHP Trinity River (#90) stop of two vehicles fleeing from a just-reported assault call.

Redding dispatch was loud & clear on VRS 03, 769.19375 (didn't have 799.19375 programmed in my scanner, as I truly didn't expect to hear anything on 700 in the wilds of Trinity County).

Just submitted the info to the DB. Not sure why the decades-old 42.44/42.28 pair is listed there as "Red2," but whatever.

PS: In 25 years of traveling across those mountains I've never seen six police cars (4 CHP & 2 TCSO) at one incident, but three of the CHP units happened to be having a powwow at Starbucks a couple hundred yards from the spot TCSO initiated the stop.
